Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switch structure, and more particularly to a switch structure that improves the operability of a lock switch and saves space.

[0002]

[Prior art]

 As shown in FIG. 2 (a), in the conventional switch structure, the leg portion 80 of the push button 60 is arranged in the case 1 that houses the substrate 2, and the switch pushing leg portion 90 of the push button 60 is The head 52 of the actuator 5 supported by the main body 4 of the lock switch 3 mounted on the substrate 2 is pressed.

The switch recess 53 of the lock switch 3 is recessed in the main body 4 as it is after being pressed. For this reason, without the spring 70 as shown in FIG. 2B, a gap G is generated between the plate 11 attached to the surface of the case 1 and the leg portion 80 of the push button 60, and the push button 60 does not work. It becomes stable. In order to eliminate this gap G, a spring 70 is attached to the outer periphery of the switch pressing leg portion 90 of the push button 60, the switch pressing leg portion 90 is lengthened, and is inserted into the insertion hole 14 (FIG. 2A) of the case 1. I was letting it.

In operation, the head 52 of the actuator 5 of the lock switch 3 is pressed by pressing the button operation part 61 of the push button 60, and the switch recessed part 53 is attached to the main body 4 on the base plate 2. Drive parts. When the pressure is released as it is, the push button 60 is pushed back to the plate 11 provided on the surface of the case 1 by the tension of the spring 70 (FIG. 2C). When the button operation portion 61 is pressed again, the actuator 5 is returned to the ascending position.

[0005]

[Problems to be solved by the device]

 In the conventional switch structure, it is possible to eliminate the gap G between the plate 11 and the leg portion 80 of the push button 60 by providing the spring 70 around the switch pressing convex portion 90. However, when the switch recessed portion 53 is returned to the ascending position, the switch pressing convex portion 90 needs to have a length m that is lower than the outer periphery 15 of the insertion hole of the case 1 forming the insertion hole 14, and the insertion length is short. If it is above the outer periphery 15 of the hole, the head 52 of the actuator 5 that recovers upward may hit the outer periphery 15 of the insertion hole and may not smoothly recover upward.

To make the head portion 52 of the actuator 5 always above the outer circumference 15 of the insertion hole by making the switch pressing convex portion 90 extremely short, the push button 60 having the spring 70 mounted thereon is arranged in the case 1. However, it is not realistic because the head 52 of the actuator 5 is very difficult to attach to the spring 70 when the substrate 2 having the switch 3 attached thereto is assembled with the case 1 to be assembled.

Further, if the diameter of the insertion hole 14 is made large so as to be suitable for raising the head portion 52 of the actuator 5, the spring 70 must be made large, and there is a drawback that the entire switch becomes large. It was When the lock switch 3 having the determined height S is mounted on the substrate 2, if the length m of the switch pressing convex portion 90 is long in this way, the whole case becomes thick and large.

[0008]

[0010]

[Action]

 The switch structure according to the present invention is a switch structure in which a lock switch having an actuator supported by the main body is mounted on a board housed in a case, and a push button for operating an actuator is provided. A state in which the return leg that comes into contact with the main body via an elastic body that resists manual pressing of the button and the actuator is pushed in during manual pressing to release the manual pressing, and the actuator returns by manual pressing again. Since the pressure leg is disposed close to the actuator, the gap between the surface of the case and the push button leg can be eliminated, and the case can be formed thin.

[0011]

【Example】

 Hereinafter, embodiments of the switch structure according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 1 (a), the switch structure according to the present invention has a push switch for operating an actuator 5 supported by a body 4 of the lock switch 3 in which a lock switch 3 is mounted on a substrate 2 housed in a case 1. 6 is provided.

The push button 6 comes into contact with the main body 4 via an elastic body 7 that resists the manual pressing of the push button 6, and the return leg portion 8 inserted into the insertion hole 16 and the actuator 5 when manually pressed. It is provided with a pressing leg portion 9 which is arranged in proximity to the actuator 5 in a state where the pressing operation is performed, the manual pressing is released, and the actuator 5 is returned by the manual pressing again.

The actuator 5 of the lock switch 3 has a head 52 that is pushed into the pushing leg portion 9 of the push button 6 and a switch diving portion 53 that dives into the body 4, and the switch diving portion that dives into the body 4. 53 drives a component (not shown) mounted on the substrate 2. An elastic body 7 such as a packing material is attached to the outer periphery of the actuator 5 on the upper surface of the main body 4 so as to resist the manual pressing of the return leg portion 8 of the push button 6.

The elastic body 7 has such a height that the lower part of the return leg 8 comes into contact when the return leg 8 of the push button 6 is returned, and the push leg 9 of the push button 6 is the head of the actuator 5. When the push-in operation of 52 is performed, the lower part of the return leg portion 8 is pushed down until the switch recessed portion 53 of the actuator 5 is embedded in the main body 4, and it has elasticity to support the return leg portion 8 (FIG. 1 (b )).

At the time of assembly, the elastic body 7 is attached to the upper surface of the main body 4 of the lock switch 3 attached to the board 2, and the board 2 on which other components are mounted is housed in a case (not shown). , The button operating portion 61 is locked to the plate 11 and fitted with the case 1 which is provided so as to project. The operation is performed by manually pressing the button operation portion 61 of the push button 6, so that the pressing leg portion 9 of the push button 6 presses the head portion 52 of the actuator 5 to cause the switch recess portion 53 to slide into the main body 4, The components (not shown) mounted on the No. 2 are driven. When the manual pressing is released as it is, the upper portion of the return leg 8 is pushed back to the plate 11 attached to the surface of the case 1 due to the restoring force of the elastic body 7 (FIG. 1 (c)). The switch recess 53 of the lock switch 3 is recessed in the main body 4 as it is after being pressed. When the button operating portion 61 is manually pressed again, the switch recessed portion 53 of the actuator 5 is returned to the ascending position.

In the embodiment, when the button operating portion 61 is manually pushed, the pushing leg portion 9 is inserted through the insertion hole 12 and when the actuator 5 is restored by manual pushing again, the pushing leg portion 9 and the actuator 5 are pushed. Since the head portion 52 is inserted through the insertion hole 12, the insertion hole 12 and the pressing leg portion 9 are formed in a slightly larger size. However, since a spring is not used, there is no effect on enlarging the entire switch. Further, if the position of the insertion hole 12 is set high enough so that only the pressing leg portion 9 can be inserted into the insertion hole 12, the insertion hole 12 cannot be made large.

When the lock switch 3 having the fixed height S is mounted, and the length M of the pressing leg portion 9 is short as in the switch structure according to the present invention, the entire case can be made thin and compact.

[0018]
